. This paper revises the bees currently considered to belong to the genus Rhectomia s.l. and proposes a species phylogeny based on morphological characters, using other Corynurina as outgroups. The results indicate that Rhinocorynura Schrottky renders Rhectomia s.l. paraphyletic. Consequently, Corynurella is removed from synonymy with Rhectomia s.s., and Paracorynurella gen.n. is proposed. The topology among these genera is: outgroup [( Rhectomia s.s. + Rhinocorynura ) ( Paracorynurella gen.n. + Corynurella )]. Nine species are assigned to Corynurella : C. brokopondoi sp.n. , C. caerulea sp.n. , C. cognata sp.n. , C. decora sp.n. , C. harrisoni (Engel), C. mourei Eickwort, C. nigra sp.n. , C. singularis sp.n. and C. triangulata sp.n. Three new species are described in Paracorynurella gen.n. : type species P. betoi sp.n. , P. excavata sp.n ., P. reticulata sp.n. ; P. difficillima (Ducke) comb.n. is transferred from Rhinocorynura . Three species are recognized in Rhectomia s.s.: R. catarina sp.n. , R. liebherri Engel and R. pumilla Moure. The male of R. liebherri is described for the first time. Keys for the identification of the genera and species are provided.
